Abstract
Three vaccines were used to compare immune effect on spleen and lymph tissue and cell line origin classical swine fever vaccine. Forty-five 30-day-old piglets were randomly selected and divided into 3 groups in a scale farm in Xiamen, meanwhile first immunization was carried out, second immunizationafter28 days, group A used spleen and lymph tissue origin classical swine fever vaccine from CQ and group B used spleen and lymph tissue origin vaccine from CD, while group C used cell line origin classical swine fever vaccine from JX, through regular tracking of antibody level to evaluate the immune effect. The results showed: The anti-body positive rate in group C herds was the highest on the 38thday after second immunization, with a significant difference in group A herds.关键词
